JUPITER, Fla. - Former Dolphin Ricky Williams is working with the Upledger Institute in Jupiter, to prove that there's a treatment for head trauma that actually works.

The bright lights, high volume, and constant movement of a football field.

Quite the contrast, inside the Upledger Institute, where the only sounds are some whispering and the whirring of a small fan..

This is not your typical huddle, but there is a football player in middle.

"I believe that this work can show change that doctors don't believe is changeable," says Ricky Williams.

The former Dolphins running back and four other former NFL players, are undergoing Craniosacral therapy in Jupiter. Developed by Dr. John Upledger, the therapy helps regulate the flow of cerebral spinal fluid throughout the body.

That's accomplished by multiple therapists listening to the needs of the patient, and working with the tissues throughout the body.

"We're not coming up with an idea of what they need," says Upledger team facilitator Chas Perry. "We're feeling their tissues and applying that, we are feeling the life of the client."

"It's just been a couple of days, and players say they are astounded how great they feel," says CEO John Upledger.

The craniosacral therapy can fix ailments throughout the body, but it's unique in what it can do for the brain.

"Football players have a headache that never really ends," says Williams. "This work allows my head to breathe."

"Our feeling is the NFL will take note and say 'There is something to this'," says Upledger. "And they will help us get our work out to a broader audience.

Upledger says this treatment not only works for people who've suffered head trauma, but he's seen success in autistic children, and Vietnam veterans as well.Thursday, July 24 2014, 12:23 AM EDTYours in health,
